What it does

Cn Open Class is an agent skill from mohitagw15856/pm-claude-skills. Use when asked 公开课怎么准备, 帮我写说课稿, 优质课比赛, 评优课, 教研课, 汇报课, 青年教师赛课, 试讲, or prepare an observed lesson in a Chinese school. Produces a 公开课 preparation pack in Chinese: a 说课稿 (说教材, 说学情, 说教学目标, 说重难点, 说教法学法, 说教学过程, 说板书) timed to the required length, the lesson's highlights (亮点) and how observers will see them, a rehearsal and 磨课 plan, contingency plans, and answers to likely 评课 questions.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Prepare an observed lesson in a Chinese school

Example prompts

  • “/cn-open-class”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  3. 磨课计划

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cn Open Class loads about 1k tokens when it runs. Until then it costs about 99 tokens; SKILL.md has 551 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~99
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Open Class and Lesson Talk (公开课准备与说课稿)

公开课, 优质课 competitions and 教研课 are how teachers are seen by colleagues, the 教研组 and sometimes the district. They come with two linked tasks: teaching a lesson in front of observers, and the 说课, a short talk explaining the design and the reasons behind it. This skill prepares both, and the rehearsals in between.

Write in Simplified Chinese unless asked otherwise. Competition rules (length of the 说课, whether slides are allowed, scoring criteria) vary by district and event; the pack is built to the rules the teacher provides, and anything assumed is marked 需核实. For the full lesson plan itself, use cn-lesson-plan first and build from it.

Required Inputs

Ask for these if not provided, otherwise infer and label the assumption:

  • Subject, grade, textbook edition and lesson
  • Occasion: 校内公开课, 区级优质课, 教研课, 汇报课, 招聘试讲, 无生上课
  • Rules: 说课 length (often 10 to 15 minutes), lesson length, slides allowed, scoring criteria
  • The lesson design (or a draft 教案), and what the teacher wants to show (a method, a 核心素养 focus, 大单元 design, technology use)
  • Class: their own class or a borrowed one (借班上课), and how well the teacher knows them
  • Timeline: days until the class, and how many rehearsals are possible

Output Structure

1. 说课稿(按规定时长,标注分钟)
  • 说教材: the lesson's place in the unit and the curriculum standard (需核实)
  • 说学情: what students know and where they struggle
  • 说教学目标: tied to the subject's 核心素养
  • 说教学重难点: and how the design addresses the 难点
  • 说教法学法: the methods and why they suit this content and these students
  • 说教学过程: each stage with its design intent (设计意图), not just the steps
  • 说板书设计: the board and what it shows
  • 说教学反思或特色: one or two honest points Written to be spoken: short sentences, signposts ("接下来我说一说…"), and timings that add up.
2. 本课亮点

Two or three highlights and the moment in the lesson where observers will see each one. A highlight must be visible in student activity, not only in the slides.

Show full SKILL.md (228 more words)Show less
3. 磨课计划

| 轮次 | 日期 | 形式 | 关注点 | 请谁听 | At least two rehearsals: one with colleagues to test timing and questions, one full run. After each, a short list of what changed.

4. 应急预案

What to do if students are silent, the technology fails, an activity runs over, or a student gives an unexpected answer; for 借班上课, a short warm-up to build rapport.

5. 评课可能的问题与回应

Five likely questions from the 评委 or 教研组 (why this method, how you know students met the objective, what you would change) with honest answers.

Quality Checks

  • The 说课 fits the required time, with timings marked
  • 说教学过程 gives the design intent for each stage, not only the steps
  • Each highlight is visible in student activity
  • There is a rehearsal plan with dates and at least two runs
  • Contingencies cover silence, technology and timing
  • Competition rules and standard references are marked to confirm

Anti-Patterns

  • A performance lesson. Rehearsing answers with students beforehand is obvious to observers and unfair to the class.
  • Slides doing the teaching. Observers look for student thinking, not animations.
  • A 说课 that repeats the 教案. It should explain why, not only what.
  • Too many activities. Observed lessons run long; plan for less.
  • Ignoring the scoring criteria. Build to them, honestly.

Example Trigger Phrases

  • "下周区里优质课比赛,初一英语,帮我写 15 分钟说课稿。"
  • "公开课怎么准备?我是新老师,第一次上校级公开课。"
  • "借班上课,课前怎么跟学生快速熟悉?"
  • "评课老师可能会问什么?帮我准备回答。"
  • "Help me prepare an observed lesson and lesson talk for a Chinese school competition."
